Experiments:

Current machine, full load time

 julia -e 'tic(); using PDMP; toc()'

This is outrageous. Chasing the culprit.

In PDMP.jl:

using Compat
using Klara.ess
using ApproxFun

using Polynomials:
        Poly,
        roots,
        polyint,
        polyval

julia -e 'tic(); using Compat; toc()'
elapsed time: 0.047637768 seconds

Negligible

julia -e 'tic(); using Klara.ess; toc()'
elapsed time: 1.290301332 seconds

That's pretty bad

julia -e 'tic(); using ApproxFun; toc()'
elapsed time: 6.580165969 seconds

That's downright awful.

julia -e 'tic(); using Polynomials; toc()'
elapsed time: 0.062788019 seconds

Negligible again.

• removing Klara.ess
• removing Distributions:Beta
• removing ApproxFun

More informations:

1. in Julia 0.5.2 it's half that time (changing Readme to reflect that for now recommended to use Julia 0.5.2 as a result)
2. apparently the problem is partly known as per JuliaLang/julia#21173
